A new water treatment plant will be created at the Swinnow Lane site to “substantially” increase production and bring employee numbers to more than 200.
The construction work will be carried out by local firm HCM Projects, part of Harris Construction Management.
Britvic’s project engineer John Marshall said the work would create one of the most advanced bottling plants in Europe.
‘Most advanced in Europe’
“We’re delighted this work is now underway, that will enable us to significantly expand our workforce and will create one of the most advanced bottling plants in Europe,” he said.
“HCM immediately understood our requirements and has a wealth of experience and an impressive track-record working on similar large-scale projects on live sites, which has made them the ideal company for us to work with.”
The site currently produces mixers and fruit juices, such as J2O, for the domestic and international market, in both bottles for consumers and bag-in-a-box containers for the hospitality industry.
The firm will also extend its existing buildings and staff car park and create a new lorry park at the facility.
Work will also include diversions to below-ground drainage; slab improvements; structural alterations; installation of food-safe wall linings and rearrangement of the existing internal mechanical and electrical service installations, HCM said.
Jason Adlam, chief executive of Harris Construction Management, said: “We are delighted to have secured this contract, which will further enhance HCM Projects’ reputation for the delivery of projects in the commercial and distribution Sector.
“Whilst we operate throughout the UK, it’s always great to be working on high profile sites close to our Yorkshire base.”
Meanwhile, the investment followed half-year financial results that earned praise from City analysts Shore Capital.
Britvic reported 7% growth in earnings before interest, tax and amortisation to £65M for the 28 weeks to April 12 2015.
